What would overturn it

A Saudi acknowledgment of damage from the Najran strikes, or a new Houthi-claimed strike, would confirm; a quiet two weeks with no further claims would overturn it.

As logged at issue

It is roughly a coin flip whether the Houthis carry out a further attack on Saudi Arabia within 14 days of Thursday's claimed Najran/Aramco strikes — the group has repeated attacks on the same Jazan refinery before, but Riyadh's continued silence on damage suggests this round may not have landed as claimed; a Saudi acknowledgment of damage would be the clearest sign the campaign is intensifying rather than mostly rhetorical.
